You can then assign default formats for each unit, so you could have degree_C formatted with one decimal place and degree_F with no decimal places. This means you can use shortened tags that do not specify the formatting to use, for example $current.outTemp.degree_C would display the current outside temperature in C with one decimal place. If you change the default format for a given unit it will applies everywhere you use tags (in that skin/report) that have implicit formatting, which is most places in the Standard and Seasons skins. If you want to step outside this for particular fields/tags you need to use explicit formatting such as $current.outTemp.degree_C.format(format_string="%.2f") if you want to display the current outside temperature in C with two decimal places.
